Choosing The Right Pneumatic Fittings to Aid Your Manufacturing Process

Does your product’s manufacturing process depends or is affected by the quality of industrial tube fittings

and valves?

Maybe the kind of fitting used on a machine is the reason why production is so slow and faulty.

Available in the market are many kinds of pneumatic fittings. Therefore choosing the right one for your application isn’t always an easy task. Factors to be considered when looking for the right pneumatic fittings are:

1.       The tubing used

2.       Operational air pressure

3.       Thread type on receiving (if any) fitting

4.       Amount of vibration the fitting will have to endure

The Most Common Fittings Available In the Market

Used largely for pneumatic applications, the fittings available in the marketplace for manufacturers are;

Compression Fittings

To make this type of fitting work, a nut or another similar device is screwed down (over the ferrule) which compresses it. This causes the ferrule to bow inwardly compressing all the components and forming a tight seal. Often used for stainless steel tubes, compression fittings are made of Stainless steel. 

Hi-Duty Flare-less Fittings

This type of compression fitting is mostly manufactured for specific high pressure and duty applications. Such applications usually exceed one thousand PSI. Hi-duty flare-less fittings are incredibly high in cost as well. 

Push-Connect Fittings

Instead of a metal ferrule (used in compression fittings), push connect fittings make use of rubber O-ring which regains its original shape when released. The elasticity of material used provides one benefit to the user. Fittings can be undone just as easily as they were created although push connect fittings can only be used on low pressure applications.

The material used to manufacture push connect fittings is stainless steel. Tube types that can be used with push connect fittings are copper, brass, nylon, steel, and polyurethane.   

Barbed Fittings

These fittings rely only on simple friction when it comes to attaching the tube with the item. This is why barbed fittings are generally used for low pressure applications as anything higher can damage the fitting.

Materials used to make barbed fittings are either thermoplastic or brass. Additionally, tubes with flexible properties like rubber or polythene are used with these fittings.
